Only 16 feet tall and 13 feet wide, this 3/4-mile tunnel was built by villagers in 1972, desperate to connect their village to the world outside the Taihang Mountains. Many of the Guoliangers died during its five-year construction.

Once named the "world's most dangerous road," El Camino de la Muerte is a 38-mile long journey through the mountains, leading from La Paz to Coroico. It is estimated that 200-300 travelers yearly die while traversing it.

The highest highway in all of the Philippines, the Halsema Highway takes about six hours to traverse. Despite its zigzag design, it has a relatively low number of deaths given its extreme altitudes, and looks fantastic.
